| A | B |
|---|
| potential energy | stored energy |
| kinertic energy | energy in motion |
| mechanical energy | energy associated with motion or position |
| Thermal enegy | Total energy in particles of an object... how hot or cold |
| Chemical energy | energy stored in chemical bonds |
| Electrical energy | moving electrical charges |
| Electromagnetic energy | Travels in waves- light; radio waves, microwaves |
| Nuclear energy | Energy stored in the core of a nucleus- Fission or fusion |
| Example: Sun | Nuclear reaction transferring to electromagnetic energy and thermal energy |
| Example: Walking person | Mecanical energy from Chemical |
| Example: Oven plugged in | Thermal and electromagnetic energy from electric |
| Example: Corn on the Cob | Chemical energy from Electromagnetic (photosynthesis) |
| A train at the top of a slope- Percentage kinetic and potential energy? | 100% potential and 0% kinetic |
| The train 1/4 the way down the slope. What percentage potential and kinetic energy? | 75% potential and 25% kinetic |
| Burning gasoline? (what energy transfer?) | Chemical energy to thermal |
| True or False: A swing stops moving because the kinetic energy is destroyed. | False! Energy is never destroyed... only transferred to friction-- heat and acoustic |
| A popper stretched and placed on the table-- example of what stored energy? | elastic potential |
| Percentage of potential energy in A pendulum at the top (highest point )of its swing? | 100% |
| Formula for Gravitational potential energy | GPE= height x mass x gravitational pull |
| Graviataional pull on earth? | 9.8 m/s squared |
